CHARLES KETTEL, OF ST. LOUIS, MISSOURI, ASSIG1\TOR OF ONE-FOURTH TOJOSEPH A. SKILLMAN, OF ST. LOUIS, MISSOURI.

HOT-WATER BOILER.

Application filed July 29, 1915.

To all whom it may concern:

Be it known that 1, CHARLES KETTEL, a citizen of the United States ofAmerica, and a resident of the city of St. Louis and State of Missouri,have invented certain new and useful Improvements in Hot-Water Boilers,of which the following is .a specification.

One of the objects of this invention is to provide an improved hot waterheating system whereby when a maximum amount of heat energy has beenattained, the surplus thereof is held or stored adjacent the boiler.

Another object of this invention is to inclose the boiler of a hot waterheating system with a sectional body of heat storing material.

A further object of this invention is to connect an ordinary waterheater tank with a hot water heating plant so that the said water heatercan be used to assist in producing a rapid heating circulation in thesystem.

Other and further objects will appear in the specification, and bespecifically pointed out in the appended claims, reference being had tothe accompanying drawings exemplifying the invention, and in which,

Figure l is a side elevation, partly in section of this improved heatingsystem. Fig. 2 is a horizontal section taken on the line IIII of Fig. 1.Fig. 3 is a vertical section taken on the line IIIIII of Fig. 1.

This improved heating system is designed so as to retain the heatingenergy in the 7 system for a long period in which event the burner whichis adapted to heat the water of the system can be turned low after adesired amount of heat has been attained in the system.

Referring to the drawings, the boiler E is mounted above the combustionchamber D, said boiler being mounted on a plate 1 which comprises thetop of the combustion chamber, said plate having a concave upper surface2 which is engaged by a portion of the cylindrical wall of the boiler.Mounted in said combustion chamber D is a gas burner T, said burnerbeing adapted to receive fuel from the supply pipe 1. Leading from'thetop of the boiler is a pair of supply pipes F, said pipes being for thepurpose of supplying the radiators (not shown). Leading from each end ofsaid boiler is a return Specification of Letters Patent.

pipe G, said return pipes being connected with the aforesaid (not shown)radiators.

Formed in the bottom 3 of the combustion chamber D is a plurality of airinlet openings, said openings being in communication with an air chamber5 which is formed beneath said bottom 8, said air chamber 5 havingcommunication with the outside air and is for the purpose of aidingcombustion in the chamber D. Mounted in one of the return pipes G is across fitting J, and connected to one branch of said cross J is a draincock K, and connected to another branch of said cross is a 'hot watersupply pipe'C which leads from ahot water tank B, said pipe C beingsupplied with a cutoff cock L. i

Leading from the top of'the tank Bv is' a discharge pipe 'V. This tankBis connected with an instantaneous'water heater 6, fuel beingsuppliedto said heater through the fuel pipe P and for supplying water to thetank B is a supply pipe U which leads from the water main.

Mounted against and inclosing the boiler E and combustion chamber D area plurality of sections A which are adapted to be mounted together andare held in position by the angle irons M. Each of the sections A areseparably constructed and are filled with a heat retaining element suchas sand which is designated by the numeral R and y when said sectionsare mounted together, the walls S thereof abut.

Secured to each of the front sections A is a door H, said door providingfor access to the combustion chamber D.

An important feature in this invention is in connecting theinstantaneous heater 6 with the piping'system as only a short while isneeded to supply heat to the radiators when getting the system into aheated condition.

The operation is as follows: When it is desired to put the radiators ofthis improved system in a heating condition, the piping system andradiators of course being emptied, the burner of the instantaneousheater 6 is started and the cock L is opened and the 'hot water isallowed to fill the pipes G, F, boiler E and radiators. The properamount of water required is indicated by the altitude gage N which isconnected to one of the pipes F. From the aforesaid it is therefore seenthat in a very short While the system can be caused to perform a heatgiving service. After the piping system and parts relating thereto havebeen filled With the hot' 7 Water supplied by the instantaneous heater6, the supply is cut oii by manipulating the cock L; at the same time itWill of course be necessary to stop the fuel supply to the burner of theinstantaneous heater 6, then the burner T is started, the furtherheating of the Water in the boiler E being then carried on by saidburner. While the burner T is supplying heat to the boiler E, the boilerin turn is giving oft heat which in turn Will be taken up by the heatretaining element which is contained in each of the sections A.

The thermometer O which is connected to one of the supply pipes F willgive the temperature of Water contained in the system.

What I claim is:

1. In a hot Water heating system, a horizontally arranged boiler, aplurality of sectional compartments adapted to be mounted in abuttingrelation to each other over said boiler, thereby inclosing the circularwall and end Walls of said boiler, each OfSitltl compartments having aheat storing element contained therein.

2. In a hot Water heating system, a boiler, a combustion chamber forsaid boiler, a plurality of sectional compartments adapted to have theiradjacent Walls abut and envelop said boiler and said combustion chamber,means for mounting said compartments together, said compartments adaptedto be filled with a combined heat receiving and restoring element.

3. In a hot Water heating system, a boiler, a combustion chamber .forsaid boiler, inlet and outlet pipes leading to and from said boiler, aplurality of sectional compartments adapted to fit over and envelop saidboiler, combustion chamber and portions of said pipes, means forclamping said compartments together after said compartments have beenengaged against said boiler and said combustion chamber, saidcompartments being filled With a heat storing element.

i. In a hot Water heating system, a horizontally arranged boiler, acombustion chamber for said boiler, a plurality of box like sectionalcompartments having curved surfaces formed thereon adapted to abut eachother and envelop said boiler and said combustion chamber, supply pipesleading from said boiler, return pipes leading to said boiler, saidsectional compartments when abutting each other adapted to on velopportions of said pipes adjacent said boiler, each of said sectionalcompartments being for the reception of a heat storing element.
